How long can China people live in China every year after they immigrate to Geneva?

The green card is the longest and the permanent residence permit is ten years. Then there is the residence permit, half of which is signed once a year. With a unit, you can go to the local bureau of foreign experts to apply for a special foreign license or a foreigner's employment permit, and you can go to the entry and exit to apply for a residence permit. Then there is the visa for visiting relatives, class L, from 6 months to 1 year. You need a marriage certificate with a China citizen, and it's easy to extend. This visa can't be used. Then there is the ordinary tourist visa. For example, if a friend wants a three-month visa, he can write a letter. He can apply for a tourist visa for about three months at entry and exit by letter. It is not difficult to put it off at first, but don't put it off in the end. For example, just go to another place and postpone your return. After three extensions, they will wonder if you are working.
